Application filed May 13, 1916. Serial No. 97,394.

To all whom it may concern:

Be it known that I, HENRY B. ELLIOTT, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Automatic Controlling .'Means for Window-Sashes, of which the following in a specification.

My invention relates to Windows and more particularly to that class of windows that have upper and lower sashes that are adapted to move upward and downward in the window frame.

The objects of my invention are; (1) to afiord means of automatically lowering the upper, and raising the lower, sash of a window; and (2) to afford means for holding the locking mechanism out of a normal position while a window is being washed, painted or repaired, and the like.

I perform these objects by means of the mechanism hereinafter described and illustrated, like reference characters representand window frame of the left hand portion thereof being cut away. Fig. 2 is a perspective view of the upper and lower sashes of said window, said sashes being placed in position so as to bring to view the perforated racks attached to the sliding and bearing faces thereof. Fig. 3 is an elevation of the inside face of the Window frame, viewed with the eye in the plane of the sash, the object being to show the lock-boxes, the operating bar and the spring key in position as attached to said frame. Fig. a is a detached edge view of said spring key. Fig. 5 is a perspective view of one of said lockboXes with all detachable parts removed, the lid of said box in its detached form being shown in the same figure with the box itself. Fig. 6 is a perspective view of one of the locking bolts of said lock-boxes, showing the channeled upper face thereof as it lies in the figure. Fig. 7 is a side elevation of the operating bar of said lock-boxes, and appearing in the same figure is a plan View of the outside end of said bar and also a plan view of a metal bearing for the inside end of said bar. Fig. 8 is a plan view and Fig. 9 is a side elevation of one of the operating arms within said lock-boxes. Fig.

10 is a perspective view, and 11 is a vertical horizontal section, of a bearing sleeve adapted to be mounted on the outside end portion of said 12 1s a plan view of one of said lock-boxes, having its lid detached therefrom and all other parts thereof in position as a workmg mechanism. Fig. 13 is a plan view of the metal bearing for the end 35 of bar H. Fig. 14 is a plan view of the outside end portion of bar H, showing the square formation in cross-section of the central portion 32 thereof, the circular formation in crosssection of the end portion 33 thereof and the smaller square formation in cross-section of the end portion 15 thereof.

A is the window frame.

B is the upper sash thereof.

C is the lower sash thereof.

D is a detached central portion of the right hand side of the window frame.

E is one of said lock-boxes. It is to be noted here that said lock-boxes are similar in construction both as it pertains to the box per se and all the parts contained thereoperating bar. Fig.

1n,. the one throughout being an exact duplicate of the other. The difference'in the boxes being in the manner-in which they are placed in the window frame.

F is the lid of said boX.

G is one of the locking bolts of said boxes.

H is the operating bar of said boxes.

I is one of the operating arms within said boxes.

J is a bearing sleeve adapted to receive the outsideend of said operating bar.

1 is a crank-like standard, integral with and projecting at approximately right angles from the outside end portion of said bearing sleeve. Said standard has the perforation 2 through the free end thereof, said perforation being adapted to receive a screw which in its turn is adapted to bind and secure said standard and sleeve to the window frame A.

3 and 4 are perforated racks, the perforations therethrough, as 6 and 7, being adapted to receive the locking-bolt G in the movement of the sash B and C upward and downward along said Window facing D.

8 and 9 are two of several similar screws adapted to bind and secure said racks to said sash. It is to be noted here that the wood of said sash lying immediately back of said perforations is gouged out at a depth suflicient to permit the catch portion of said locking-bolt G to properly enter said perforations. Screws, as 11 and 12, are adapted to bind and secure said lock-boxes to 'said window facing D.

13 and 14, taken together, constitute a spring key, the portion 14 thereof being adapted to receive the squared end portion 15 of the locking bar H, the spring portion 13 thereof being adapted to enter a longitudinal slot in the end of the portion 14 thereof and revolve on the rivet 16 and engage the window frame at points as 17 and 18 and hold said locking bolts out of locking position, the engagement at point 17 giving a free up and down movement to sash C and the engagement 18 giving a free up and down movement to sash B.

20 and 21 are perforations adapted to receive screws as 11 and 12.

22 is a bearing bracket adapted to support bolt G on one side. This bracket is punched out of the side of box E and is so positioned, that the end 23 of said box becomes a bearing for and supports the other side of said bolt which moves back and forth through slot 24.

25 is adapted to receive bar H and admit of a free rocking movement thereof.

26 is a perforation similar to 25 and in the lid of said box and so positioned as to aline therewith.

27 and 28 are rectangular perforations through the ends of said box and are adapted to receive the catches 29 and 30 respectively. It is to be noted here that one 'corner of the catch portion 10 of bolt G is rounded off thereby adapting said bolt after having entered one of the perforations of racks 3 or 4 to mount said racks independent of any action of said bar H.

3l is a plan view of the outside end portion of bar H showing the square formation in cross-section of the central portion 32 thereof, the circular formation in crosssection of the end portion 33 thereof and the smaller square formation in cross-section of the end portion 15 thereof, said boxes being adapted to be mounted on said portion 32, said sleeve being adapted to be mounted on said portion 33 and said key being adapted to engage said portion 15.

34 is a metal bearing for the end 35 of said bar, said bearing being fitted into and seated at the bottom of a recess in said window frame, said recess being adapted to receive the inside end portion of said bar, the end 35 thereof being in engagement with said bearing.

36 is a square perforation through one end of the arm I and is adapted to receive said bar H. The other end 37 of said arm is reduced in width and is thereby enabled and adapted to enter channel 38 of said locking-bolt G and freely engage one or the other of the vertical sides 39 and 40 thereof.

41 is the beveled end of the sleeve J and is adapted to abut the shoulder 42 of bar H. Thus it is seen that said sleeve in addition to being a bearing for the portion 33 of said bar is at the same time adapted to hold said bar in position in said window frame.

43 is the bore in said sleeve that is adapted to receive the portion 33 of said bar and 44 is the bore overhanging the portion 15 of said bar and is adapted to receive the squai'ei'ecessed end 14 of the key 13 and 14.

45 is a spring having one of its ends attached to the side of said box E by means of the rivet 4G. The free end of said spring is adapted to engage the side 40 of said bolt G and hold it in a normal position and bring it back to a normal position when pressed inward either by the arm I or the edge of a perforation in said racks 3 and 4.

Having thus described my invention in detail and by illustrations, I will now describe it as a working mechanism.

The lock-boxes E having their bolt ends lying in opposite directions and being so positioned that each bolt can be operated by the same operating bar H, and the movement of arm I away from spring 45 being non-operative, it follows that a turn on key 13 and 14 in one direction will move the bolt Gr out of engagement with one of the racks 3 and 4, and a turn of said key in the other direction will move the bolt G out of engagement with the other one of said racks. The combined weight of the two weights supporting sash B being some less than the weight of the sash, and the combined weight of the two weights supporting the sash 0 being greater than the weight of the sash, if it is desired to let the sash B down at the top, a turn on said key to the right moves said bolt out of engagement with rack 3 and sash B descends and can be stopped and held at any point by releasing the pressure on said key. Likewise, also, a turn to the left on said key will move said bolt out of engagement with rack 4 and sash C will rise and can be stopped and held at any point by releasing the pressure on said key. The sash B when down can be raised by lifting it upward with .the hands, and, likewise, when sash C is up, it can be lowered by pressing it downward with the hands. In washing, or painting, or repairing, said sash, a free movement in either direction, or rather in both directions, can be given either sash by turning on said key in the desired direction and by bringing the part 13 of said key over against the window casing, the resiliency of the spring admitting of such an operation, said casing holding said key in that position and the looking bolt out of engagement with said rack for any desired length of time.

Having thus described my invention in detail, by illustration and as a Working mechanism, What I claim is In automatic controlling means for window sash and in combination; a window frame; sash pulleys attached thereto; ropes mounted on said pulleys; Window sash hav ing perforated racks attached thereto attached to one end of said ropes and weights attached to the other end; the weight of the upper sash being greater than that of the combined weight of the weights controlling the same; the Weight of the lower sash being less than that of the combined Weight of the weights controlling the same; sash lock-boxes similar in construction attached to said frame, the bolt of one box being adapted to engage the rack attached to one sash and the bolt of the other box being adapted to engage the rack attached to the other sash, said boxes being positioned on the overlapping line of said sashes, one of fill said boxes having its bolt end upward and the other box having its bolt end downward;

' a sash lock-box operating bar attached to said look-boxes said bar being adapted to operate the locking bolt in each of said boxes, one of said bolts being moved by a turn of said bar one Way and the other one of said bolts being moved by a turn of said bar the other Way, said bar having an endbearing metal piece at one end and abearing sleeve at the other; a lock-box operating bar key having a spring portion adapted to engage said Window frame and hold said locking bolts out of a normal locking position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
